Triptych Games’ president David Riegel has revealed in a podcast over on the official Duke Nukem Forever site, that the game was 75-80 percent complete when 3D Realms shut its doors back in 2009.

Riegel, who was at Ion Storm before moving on to 3D Realms, admitted that the percentage of the game finished, was an “uneven” percentage.

“When 3D Realms shut its doors in May, I would say the game was maybe about 75-80 (percent) compared to what it is today,” he said.

“But it was interesting because it was a kind of an uneven 80 (percent). Most of the characters didn’t exist. NPC behavior didn’t really exist, like no head tracking or eye tracking, no lip syncing, none of that. No music, no ending: there was a planned ending but it wasn’t really there.”

Riegel went on to form Triptych Games with other, former 3D Realms members in 2009.

Duke Nukem Forever is due out on June 14 in the US and on June 10 everywhere else in the world.
